What Is Glycolic Acid?
Glycolic acid is an alpha-hydroxy acid (AHA) used in skincare to help exfoliate the skin's surface, supporting the removal of dull surface skin cells and the appearance of a smoother, more radiant-looking complexion over time.
It is one of the most widely used AHAs in cosmeceutical exfoliation formulations designed to help support the appearance of more refined skin texture and a brighter-looking complexion with consistent use.
How Glycolic Acid Works on Skin
Glycolic acid is an AHA (alpha hydroxy acid) that works by chemical exfoliation, helping loosen the bonds that hold dead surface skin cells together. This allows them to shed more easily, revealing fresher-looking skin underneath and supporting a more refined appearance.
Thanks to its relatively small molecular size, glycolic acid is considered one of the more active AHAs. It’s believed to penetrate the surface layer efficiently, helping to improve the look of skin texture and tone with consistent use.
What Skin Concerns May Glycolic Acid Help Improve the Appearance of?
Uneven skin tone and pigmentation
Glycolic acid is included in cosmeceutical formulations for its potential to help improve the visible appearance of pigmentation and uneven skin tone. By supporting the shedding of dull surface skin cells, it may help skin appear more even and brighter-looking over time with consistent use. Results may vary between individuals.
Dull or rough skin texture
For skin that looks dull or feels uneven, glycolic acid may help support a more refined-looking surface through chemical exfoliation, potentially helping skin appear smoother over time with consistent use.
The appearance of fine lines
Glycolic acid may help support a smoother-looking skin surface, which may assist in softening the visible appearance of fine lines over time with consistent use. Results may vary between individuals.
Enlarged pores appearance
Dry, crepey skin under the eyes can make everything look more tired than it really is. Hydrating eye creams deliver moisture where it’s needed most, helping the skin feel softer, smoother, and more comfortable.
Post-blemish marks
Glycolic acid may help improve the visible appearance of post-blemish marks by supporting a more even-looking skin tone over time. Results may vary between individuals, and consistent use is recommended.
Glycolic Acid vs Other AHAs
Glycolic acid is known for having the smallest molecular size among AHAs, which is why it’s often chosen for targeting skin texture and uneven skin tone. It works at the surface level to help refine and smooth the skin’s appearance.
Lactic acid, another alpha hydroxy acid, has a slightly larger molecule, making it a gentler option. It’s often preferred by those newer to AHAs or those looking for a more hydrating exfoliation experience while still supporting smoother-looking skin.
Salicylic acid sits in a different category altogether. It’s a BHA (beta hydroxy acid), not an AHA. It’s oil-soluble and typically used in routines focused on congested or blemish-prone skin.
Each ingredient offers a different approach, and they’re often used together in well-balanced formulations like Skin Doctors Renewing Night Peel.

Who Is Glycolic Acid Suitable For?
Glycolic acid can be a great fit for those looking to improve the appearance of uneven skin tone, dull skin, and rough skin texture, as well as soften the look of fine lines and enlarged pores.
It’s generally suitable for most skin types when introduced gradually, but those with very sensitive, reactive or rosacea-prone skin may prefer to proceed with caution or explore gentler alternatives.
A patch test is always recommended before first use, and if you have a diagnosed skin condition or specific concerns, it’s best to consult a healthcare professional before adding glycolic acid to your routine.
Frequently Asked Questions
What does glycolic acid do for your skin?
Glycolic acid helps exfoliate the skin's surface by supporting the removal of dull surface skin cells, which may help improve the visible appearance of skin texture, tone and radiance with consistent use. Results may vary between individuals.Is glycolic acid safe for sensitive skin?
It may be suitable for sensitive skin if introduced gradually. Always patch test first and begin with lower frequency use. Those with sensitive skin may find lactic acid a more suitable starting point, and those with a diagnosed skin condition should consult a healthcare professional before use.Can I use glycolic acid every day?
Daily use isn’t usually recommended when starting out. Begin with 2–3 nights per week and increase gradually depending on how your skin responds.Do I need sunscreen after using glycolic acid?
Yes. Glycolic acid may increase temporary sun sensitivity, so applying a broad-spectrum sunscreen with SPF the next morning is essential.Can glycolic acid be used with retinol?
Some formulations, like Skin Doctors Renewing Night Peel, combine actives in a balanced way. If using separate products, introduce gradually and avoid layering multiple strong actives in the same routine.How long before I see results from glycolic acid?
With consistent use, improvements in skin texture and tone may become visible over several weeks. Results can vary depending on individual skin type and routine.
